occurred in Mexico ; they are large and conspicuous insects with tho 

 antennae lender than the body, especially in the male, rather robust at 

 base, and gradually tapering to apex ; the thorax is armed with a sharp 

 spine on each side, and the anterior coxal cavities are open behind; the 

 elytra are convex, and the legs rather long, with the tibiae somewhat com- 

 pressed ; about half-a-dozen species have occurred in Europe. 



The larva of 31. sartor is described by Schiodte (Pars ix. p. 435); it is broad in 

 front and considerably narrowed behind, nnd differs from tlie majority of the Lmniiihu 

 in being furnished with very minute legs ; the anal segment is transverse with the 

 inferior portion sulcate in the middle ; it is found in pine wood. 



I. Seutellum entirely clothed with yellowish-white pubescence j 



average size larger M. SAKTOB, F . 



II. Scutcllum clothed with whitish or yellowish-white pubescence 



with a smooth central line ; average size smaller M. S0TOB, L, 



M. sartor, F. Black, with the elytra slightly aeneous ; antennae 

 long ; thorax with a lateral spine on each side ; scutellum entirely 

 clothed with yellowish- white pilose pubescence ; elytra obsoletely im- 

 pressed transversely in front, rugosely punctured at base, and very 

 obsoletely punctured but thickly pubescent towards apex ; in the male 

 the elytra are slightly narrowed to apex and are immaculate, and the 

 antennas are more than twice as long as the body and black ; in the 

 female the antennae are not much longer than the body and ringed with 

 greyish pubescence, and the elytra are parallel-sided and variegated with 

 a few spots of grey pubescence. L. 18-30 mm. 



In timber, and on trunks of trees ; very rare, and probably an importation ; Lon- 

 don, Devonshire, and Norfolk (Stephens); Repton (K. Brown) ; two specimens from 

 Cambridge Feus (S. Stevens) ; one specimen taken by a groom in a stable at Boothby 

 Graffoe Rectory, and given to Dr. Power by Miss Fullertou ; one in a timber-yard near 

 Taunton ; Manchester. 



M. Butor, L. Black, rather convex, mottled with pale pubescence 

 on the upper side, and thickly pubescent beneath ; rather smaller on tho 

 average than the preceding species, and easily distinguished by the fact 

 that the scutellum has a smooth glabrous line in the middle, the rest 

 being clothed with thick whitish pubescence ; thorax with a stout acute 

 spine on each side ; elytra even, slightly aeneous, closely punctured, and 

 together with thorax variegated with a number of spots of yellowish- 

 grey or greyish pubescence, which are more numerous in the female. L. 

 1G-26 mm. 



M.tlu with the antennae more than twice as long as body, black ; 

 female with the antennae a little longer than the body, ringed with white, 

 and with the elytra more thickly spotted with whitish pubescence. 



In timber, and on trunks of trees ; very rare, and probably an importation like the 

 preceding ; Colney Hatch, and Norwich (Stephens) ; Burton (E. Brown) ; timlx-r- 

 ynrd near Taunton; Manchester; Newcastle (one specimen taken in the street) 

 (Dinning).
